LEROY W. SIMMONS, OF BROAD RIPPLE, INDIANA GULTIVATOB. 7

To all whom it may concern:

Be it known that I, LEROY W. SIMMONS, a citizen of the United States, residing at Broad Ripple, in the county of Marion and State of Indiana, have invented a new and useful Cultivator, of which the-following is a specification, reference being had to to improvements of the gangcultivator described in Letters Patent of the United States No. 1,107,856, grantedto me August An object of the invention is to provide an improved beam and standard construction that shall obviate the trouble and an noyance entailed by the break devices hitherto provided for preventing injury to parts of the cultivator in case the plows or shovels catch on roots or other obstructions inthe ground.

Another object is to provide a simple,

y reliable and durable beam-break structure which shall permit the operator to immediately readjust the parts of the structure so as to be normal and proceed with the work without delay and loss of time following each break. of the connections between the shovels and the beam.

A further object is to provide improved means for connecting the shovel to the beam of a cultivator, which shall permit of adjustment to vary the degree of resistance to the breaking of the joint connections, in order to adapt the cultivator to various con ditions of ground to be cultivated.

A still further object is to provide improved means for connecting the, shovel standards described in the above-mentioned Letters Patent to a draft beam so as tobe reliable and powerful while permitting the shovels to drag over unyielding obstructionswithout injury to any ofthe parts'of the structure. i

With the above-mentioned and other objects in view, the invention consists in an "improved cultivator beam including the Specification of Letters Patent.

Application filed. July 24, 1915. Serial No. 41,719. V

standard thereof and comprising means for pivotally' connecting the standard to the beam, and also means for yieldingly securing the standardto the beam, so that "the standard may swing back and again be automatically clutched by the beam; andthe invention consists further in the novel parts, and the combinations and arrangements of parts, as hereinafter particularly described and further defined in the accompanying?- claims.

Referring to the drawings,-Figure 1 is a top plan of a cultivator gang constructed substantially in accordance with the inven tion; Fig. 2 is aside elevation of the main 'beam'and the shovels of the gang; Fig. 3 is a fragmentary section approximately on the line AA on Fig. 2 with the standard in changed position; Fig. 4 is a perspective view of one of the parts of the beam; Fig;

5 is a perspective view of one of the movable clutch parts of the beam as preferably constructed; Fig. 6 isa sectional plan on the line B B on Fig; 2; and, Fig. is a vertical central section of the improved beam andits standard carrying a single shovel approximately in the position resulting from engagement with an obstruction;

In the di-iferent figures of the drawings, similar reference characters indicate corresponding elements or features of construction herein referred to.

For the purpose of clearly describing the invention one gang of a cultivator constructed in accordance with the invention is'.

illustrated, the gang "comprising a main beambar consisting of a forward portion 1,

a main or body portion 2, and a rear portion 3, the forward portion being adapted to be connected to a 'sulky or a draft appliance, as is customary, soythat the beam shall be drawn forward in approximately horizontal position and if carried to permit the rear end of the beam to be elevated while the supward'from the rear portion 3 and has a hinge jaw '7 on its upper end that is provided with a hinge pin 8. A. standard 9 is provided which has a hinge member 10 that is connected to the pin 8, so that the standard may swing toward or from the rear end portion 3 which is provided with a bolt 11 whereby a beam part 12 is secured to the portion 3, said part having a recess 13 into which the end of the portion 3 extends, and a bolthole 14, Fig. 4, through which the bolt 11 extends. The beam part 12 has laterally and rearwardly extending wings 15 and 16 thereon that are curved on their inner sides, and together with the rear end of the part 12 constitute a semi-circular seat 17 to receive and guide the standard 9. The beam includes also two hinge members 18 and 19 that are secured to opposite sides respectively of the beam bar rearward of the jaw 5, a securing bolt 20 being suitably used for the purpose. The hinge members are provided with vertical hinge pins 21 and 22 respectively to which two draft bars 23 and 24 are respectively connected so as to normally extend against the rear portion 3 of the beam proper. The standard 9 has a cylindrical portion that is normally in position against the seat 17, and the draft bars have semi-circular recesses 25 and 26 in their inner sides that receive and embrace the opposite sides respectively of the standard and constituting lugs for normally drawing the standard forward with the beam. Rearward of the recesses the draft bars have divergently extending guide faces 27 and 7 rear portion 3 of the beam bar. the rod pref erably having screw threads 32 throughout its length and being screwed into the bar so as to be fixed thereto and practicallv form two adjusting screws on opposite sides respectively of the beam bar and on which tension springs 33 and 34 are placed so as to bear against the draft bars 23 and 24 respectively, the tension of the springs being adjusted by means of nuts 35 and 36 placed on the end portions of the rod 31 at the outer ends of the sprin s. The tension of the springs may be regulated so as to retain the standard 9 in connection with the rear end of the beam with greater or less force, as may be desired.

Preferably each standard is equipped, as described in said Letters Patent. with a yoke 37 which has two stems or standard portions 38 and 39 to which two shovels 40 and 41 are respectively connected so as to be adjustable rotatively, the yoke being adjustable rotatively on the standard 9, thus affording advantages when close cultivation is desired, but in some cases a single cultivator shovel 42 may be adjustably connected directly to the standard 9, as illustrated in Fi fiear the forward portion 1 a. head 43 is secured to the beam and has pivots 44 and 45 to which auxiliary beams 46 and 47 are connected. The beam 46 is adjustably connected with the main beam, preferably by means of a tie-rod 48 adjustably connected to the beam 46 by means of nuts 49 and 50 and to the main beam by means of nuts 51 and 52, a similar tie-rod 48 being connected to the main beam 47 by means of nuts 49 and 50 and to the beam 46 by means of nuts 51 and 52, the nuts being screwed onto the rods and arranged in pairs so as to engage opposite sides of the beams. The auxiliary beams are equipped with cultivator implements like the main beam and constructed identically as above described, so that a yoke 37 having shovels 40 and 41 is connected to the beam 46, and a yoke 37 having shovels 40 and 41 connected thereto is connected with the beam 47 according to the improved construction above described, therefore requiring no further explanation.

It should be understood that the form of the cultivator shovels and the means for connecting them to the standard 9 may be variously modified without affecting the structure and mode of operation of the devices for practically connecting the cultivator implements to the beams of the machine.

In practical use the beams are drawn forward, as is customary, and in case a shovel is forced into contact with a root or other obstruction in its path the obstruction may in some cases be forced aside or cast up from the soil, but when too large or too securely fixed in the ground to be dislodged by the shovel without liability to cause in jury to parts of the cultivator the standard 9 is caused to swing on its hinge pin as the beam is drawn forward, the shovel being dragged over the top of the obstruction, after which the operator lifts the gang clear of the ground and with one foot kicks the standard 9 back to its normal position and then lowers the beams and proceeds with the operations. During the movement of the cultivator in normal operation the fingers 15 and 16 prevent the standard from being strained laterall and becoming released from the clutch of the draft bars.

Having thus described the invention, what is claimed as new is 1. A cultivator beam having an open seat on its rear end and also a pivot supported substantially above the rear end, a standard connected to the pivot and normally extending against the seat, and a draft device mounted on the beam to elastically swing horizontally and provided With a lug normally engaging and removably holding the standard to the seat.
